Exam is good, but still too strong sometimes. I found that I could tolerate 12.5 , 6.25, (repeat) in PCT fine, but anymore would elicit painful symptoms. Although Erase isn't as good, it's a lot easier to dose. I switched to Erase @ 50mgs for the last few weeks of a long PCT.
I'll also be running Trest later this year, hope it's as good for me as it has been for you!
